UN R83 Supplement 19 (06 series) · UNECE Regulation No. 83 (ECE R83) — Uniform provisions concerning the approval of vehicles with regard to the emission of pollutants according to engine fuel requirements.
UN R83 — Supplement 19 to the 06 series of amendments
Supplement 18 → 19
- What changed
- In new paragraph 3.2.7. of Annex 4A, the test vehicle must have the group's daytime running lamp system with the highest electrical energy consumption. The daytime running lamps as defined in paragraph 2. of Regulation No. 48 must be switched ON during the test cycle.
- For tests according to this Regulation after “[xx-xx-20xx]”, new paragraph 3.2.8. requires the rear position lamp setting that applies at ambient light above 7,000 lux.
- Paragraph 3.2.1.2. of Annex 11 now refers to “engine coolant temperatures” for OBD monitor disablement. New paragraph 6.5.3.3.1. allows ISO 27145 or SAE J 1979-2 as an option instead of ISO 15031-5 for the transmission of OBD relevant information.
- Why
- The proposal aims to harmonize the 06 and 07 series of amendments to UN Regulation No. 83. It also aims to make type-approval test conditions consistent with the introduction of the 08 series of amendments to UN Regulation No. 48.
- UN Regulation No. 48, 08 series, is aiming to allow rear position lamps and other lamps to switch OFF in ambient light above 7,000 lux.
- The experts from OICA proposed SAE J 1979-2 in an additional paragraph for Series 05 and 06, because their structure differs from Series 07.
Q1What changed13 changes
Daytime running lamps in the test (Annex 4A, new para. 3.2.7.)
Under new paragraph 3.2.7., the vehicle to be tested must have the daytime running lamp system with the highest electrical energy consumption. The comparison is among the systems fitted by the manufacturer to vehicles in the group represented by the type-approved vehicle. The manufacturer must supply appropriate technical documentation to the type-approval authorities in this respect. The daytime running lamps as defined in paragraph 2. of Regulation No. 48 must be switched ON during the test cycle.
Rear position lamps in tests (Annex 4A, new para. 3.2.8.)
New paragraph 3.2.8. applies to tests according to this Regulation performed after “[xx-xx-20xx]”. In these tests, the rear position lamps must be set to the operating condition which is applied at ambient lighting conditions exceeding 7,000 lux. The text gives the vehicle's dynamometer operation mode as an example. A new footnote says “Date to be replaced by the date of entry into force of this proposal when known”.
Engine coolant temperatures and OBD monitor disablement (Annex 11, para. 3.2.1.2.)
In the first sentence of paragraph 3.2.1.2., “ambient or engine temperatures” becomes “ambient or engine coolant temperatures”. The second sentence now says “other ambient or engine coolant temperatures” instead of “other ambient temperatures”. A new sentence says: “Engine coolant temperature is only deemed subject to approval, if it is used as a substitute to ambient temperature.” The values 266 K (-7° C) and 2,500 metres do not change.
On-board evaluation test results and in-use performance data (Annex 11, Appendix 1, para. 6.5.1.3.)
Paragraph 6.5.1.3. now refers to emission control systems for which specific on-board evaluation tests are conducted “according to this annex”. The reference to the specifications given in paragraph 6.5.3. now adds “of this appendix”. In the text on data stored in relation to OBD in-use performance, the reference to paragraph 6.5.3. now ends with “of this appendix”. Before, this reference ended with “of Appendix 1 to Annex 11 of this Regulation”.
ISO 27145 or SAE J 1979-2 as an option (Annex 11, Appendix 1, new para. 6.5.3.3.1.)
Under new paragraph 6.5.3.3.1., ISO 27145 or SAE J 1979-2 may be used as an option instead of ISO 15031-5. This option is for the transmission of OBD relevant information. The paragraph names ISO 27145 dated 2012-08-15 and SAE J 1979-2 dated April 2021.
Responsible standardisation body for diagnostic data (Annex 11, Appendix 1, paras. 6.5.3.3. and 6.5.3.4.)
Paragraphs 6.5.3.3. and 6.5.3.4. now say “the responsible standardisation body” instead of “a national standardisation body”. The vehicle manufacturer must provide this body with the details of any emission-related diagnostic data related to this Regulation. This applies to data not specified in ISO DIS 15031-5.

- GRPE, 87th session (January 2023)
Reasons
The proposal aims to harmonize the 06 and 07 series of amendments to UN Regulation No. 83. For this purpose, paragraph 3.2.7. is integrated in the 06 series of amendments. Paragraph 3.2.7. was modified to fit with the wording of UN Regulation No. 48.

“Paragraph 3.2.7. is integrated in 06 series of amendments to UN Regulation No. 83 to harmonize 06 and 07 series of amendments.”
“This paragraph was modified to fit with UN Regulation No. 48 wording.”
The proposal also aims to make type-approval test conditions consistent with the introduction of the 08 series of amendments to UN Regulation No. 48. The 08 series of UN Regulation No. 48 is aiming to introduce the possibility to switch OFF rear position lamps and other lamps. This applies when ambient light conditions outside the vehicle are above 7,000 lux, to avoid unnecessary fuel consumption. The vehicle settings for the dynamometer operation must be independent of the light conditions in the laboratory. For this reason, a “trip” is proposed to represent ambient light conditions with an illuminance above 7,000 lux.

Proposer's reason (informal document GRPE-87-13-Rev.2)
GRPE-86-12 proposed the introduction of SAE J 1979-2 for Series 05, 06 and 07 of Regulation No. 83. Series 05 and 06 have a different structure from Series 07. For this reason, this proposal introduces the new standard in an additional paragraph in Series 05 and 06.
Submitted by Experts from OICA. Working party adoption: ECE/TRANS/WP.29/GRPE/87, para. 15.
Sources (2)
“In GRPE-86-12 the introduction of SAE J 1979-2 was proposed for Series 05, 06 and 07 of Regulation No. 83.”
“Due to the different structure of Series 05 and 06 compared to 07, this proposal introduces the new standard to additional paragraph in Series 05 and 06.”
Proposer's reason (informal document GRPE-87-13-Rev.2)
The words “or engine” were missing in the second sentence of paragraph 3.2.1.2. The change aligns it with the first sentence, to avoid misunderstanding and ambiguity. Engine coolant temperature is sometimes used as a substitute for ambient temperature. In this case, it is evaluated once after a longer engine shut off phase. Only in this case is an approval necessary, because this is the only case where an OBD monitor is disabled for the complete trip.
